HEATER FOR GASEOUS FUEL.

Application lerl November 17, 1913.

T0 all ic/iom it may concern Be it known that I, Serri MULvANI-', a citizen of the United States, residing at Inglewood. California. have invented a new and useful lleater for Gaseous Fuel, of which the following is a Specification.

This invention relates to a charge forme.

ing device to break up more thoroughly the liquid fuel, and at the same time heat it Sulli- 'ciently to vaporize the heavier oils such as tion engines now on the market, and which is adapted to utilize the heated blast from the exhaust to heat in an efficient manner the spray of liquid fuel. This device provides a large heat-radiating area incomparison to its compact and simple construction. The entire fuel Jfed to the engine may be made to take a course that brings it into immediate contact with said heat-radiating area.

The invention comprises an improved heat-radiating device and also improved means to conduct heated gas from the exhaust to said device to heat the same.

Referring to the accompanying drawings, which. illustrate the i1ivention,-l `igtu'e 1 is an elevational view of a portion of an internal combustion engine, its carburetor and fuel pipes being shown, and the device which forms the subject matter of this invention being shown connected therewith, said device being sectioned. Fig. 2 is an enlarged side elevation of the heater, part of the casing being broken away. Fig. 3 is an edge view of the heater, partly in section. Fig'. 4 is an enlarged detail view of the means for catching the exhaust gas.

Referring in detail to the drawings, the main fuel supply pipe is formed in two sections 5 and G between which is inserted a casing 7 that contains a chargeheat-ing and vaporizing body 8. fluid body 8 is heated by passing theretlirough a portion ol' the exhaust gases from the manifold pipe S) of the engine 11. To this end a supplemental exhaust pipe l2 is provided at one endv with a geest-neck 123. the end portion of which is tapped into the exhaust pipe J and has with- -in said pipe 9 a lateral inlet opening 1l' directed toward the exhaust. The other end of pipe l2 is led through the edge of casing Specication of Letters Iatent. Patnfcdl Feb, 16, 1915.,

Serial No. 801.417.

15.y The yother Side vof body 8 (oppositeA pipe i12) is vprovided with an outlet; pip'e'l.

.Hence znconsiderable portion of the heated exhaust passes lcontinuously through they drulnS. The sides of the drum 8 extend into the casing T beyond the edge of theinf take openingforined bythe pipe 5, withl the result thatthe incoming fuel is deflectedy outwardly from said intake and is compelled to pass into .close proximity to the heating drum 8. The liquid fuel, being heavier than the atmosphere, will all be thrown against the end of said heating drum` to be retained between the ribs 15 until vaporized.

The pipe 12 which conveys the heated gas to the charge forming device proper is formed in two sections, 12a and 12b which are united by Screw-threaded coupling member 17, as shown in Fig. 1. Said coupling member 1'? coperates with the gooseneclc portion 13 of the pipe 12 to provide a device that can be very readily connected up with automobile engines now on the market. The gooseneck arrangement permits the hole for receiving thepipe 12 to be tapped through the side of the manifold pipe 9 opposite the charge forming device 7. rl`he goose-neck 7 can he rotated to bring the open end thereof into position for insertion into manifold pipes considerably lateral to pipe 12, thereby adapting the heater for ready application to origines di tfering in design. Then after the extreme end portion of the pipe 12 has been inserted through the wall oi the pipe 9 the section 12et of the pipe 12 readily drawn toward the section 12b of said pipe in the act of coupling said sec-- tions together.

ldesignates a carbureter of well known make having a distillate feed pipe '22 and needle valve Q3 from which the suction of the engine draws in the distillate in the form of partly vaporized spra) and throws it forcibly against the/ribbed portion 15 of the drum S thereby in an ellicient manne.:` vaporizing and heating the distillate or other heavy liquid fuel used.

lipc 5 is provided with a throttle valve gasolene feeding device for use in starting is illustrated in Fig. 1. From the gaso lene tank 3l a conduit 32 leads to the sprayy said casing and through said drum to heat f chamber 33 which communicates with ,the supply pipe 6 between the .casing 7 and thelatter, one of the `fiat portions of-said drum'being directed toward said inlet-and beingiprovided with ribs to retain the liquid portion of the fuel, there being.,r an annular space around said drum between the same and the inner Wall of said casing.'

' 2." In a'heater for gaseous fuel, a charge forming element proper, and a heatingr pipe to conduct heated gas from the discharge manifold pipe of an engine to the interior of said heating element to heat a portion vthereof, said heating pipe consisting of two sections united together by a coupling, they intake end'of said heating pipe comprising a laterally adjustable gooseneck the tip portion of which is tapped into the Side of said v` manifold pipe opposite the charge forming device proper, there being a lateral opening in the end portion of said heating pipe within the manifold pipe, said openingl being" directed toward the exhaust which passes through the manifold pipe.

In testimony whereof I have vhereunto signed my name in the presence of two subscribing Witnesses at Los Angeles, in the county of Los Angeles and `State of California, this 8th day of November, 1913.
